如何在Python中将某个RGB值赋给其他一些RGB值中最接近的值

import math

def euclidean_distance(rgb1, rgb2):
    r1, g1, b1 = rgb1
    r2, g2, b2 = rgb2
    distance = math.sqrt((r2 - r1)**2 + (g2 - g1)**2 + (b2 - b1)**2)
    return distance

def find_closest_rgb(rgb, rgb_list):
    closest_distance = float('inf')
    closest_rgb = None
    for rgb_value in rgb_list:
        distance = euclidean_distance(rgb, rgb_value)
        if distance < closest_distance:
            closest_distance = distance
            closest_rgb = rgb_value
    return closest_rgb

rgb_list = [(255, 0, 0), (0, 255, 0), (0, 0, 255), (255, 255, 0), (0, 255, 255)]
rgb = (100, 50, 200)
closest_rgb = find_closest_rgb(rgb, rgb_list)
print(closest_rgb)
